I used to play indie games quite a bit about an year ago. However, I have lost faith on indie developers. Firstly most of these games are clones. There are very few original ideas. Even when there are new ideas the problem is that these games are targeted at non-gamers. The developers just coerce tons of badly developed "creative" ideas with "cool" graphics. A few times I was really left wondering whether the developers really play tested their own game even once.
Also PopCap games' status as fresh and innovative is dubious to me. They may have done a few good ideas but when they blatantly copy their games from a small Japanese developers, without any permission, and then refuse to give them any credit, its a bit sad. My suggestion to you too is that please don't copy an idea without the permission of the original developer
. Hope you can come up with truly creative and fresh ideas.
